In this paper, we demonstrate how to capture the robustness of a transportation network in the case of degradable links represented by decreasing capacities. In particular, with the use of Bureau of Public Road user link travel cost functions, we propose two relative total cost indices to assess transportation network robustness in the case of travel behavior associated with either user-optimiz...

The objective of this project was to develop a structural index for use in network-level pavement evaluation to facilitate the inclusion of the pavement’s structural condition in pavement management applications. The primary goal of network-level pavement management is to provide the best service to the users for the available, often limited, resources. Pavement condition can be described in te...

guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of intelligent transportation systems (its). nowadays, many complex systems can be controlled by using multi agent systems. adaptation with the current condition is an important feature of the agents. in this research, formulation of dynamic guidance for vehicles has been investigated based...

rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. in the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. with traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. four s...

In these days, remotely sensed imagery has been widely used for GIS-T (Geographic Information Systems for Transportation). As for this approach, topological measure and spatial metrics of transportation network structure such as road layer can be considered as one of important factors in urban transportation analysis. Related to this measure, it is known that the connectivity such as alpha inde...

in a military organization, the role of transportation should be much more strong and strategic character for the organization. in this context, the evaluation of operating ability of transportation and eliminate defects and problems, can help the managers to improve performance and increase the effectiveness and efficiency of transportation in the assigned missions. in this study, a model is p...

One abstract method for the study of network transportation is proposed in this paper. By interpolating the properties of the edges that constitute network into the two leading parameters of the nodes, this method can abstract the configuration of real-life transportation networks without losing the influence of the distance and the capability of the physical facilities, which are essential par...
